Crater Detection Via Genetic Search Methods To Reduce Image Features, Joseph Paul Cohen

Graduate Masters Theses

Recent approaches to crater detection have been inspired by face detection's use of gray-scale texture features. Using gray-scale texture features for supervised machine learning crater detection algorithms provides better classification of craters in planetary images than previous methods. When using Haar features it is typical to generate thousands of numerical values from each candidate crater image. This magnitude of image features to extract and consider can spell disaster when the application is an entire planetary surface. One solution is to reduce the number of features extracted and considered in order to increase accuracy as well as speed. Feature subset selection …

Producing Space: Block-By-Block Change In A Gentrifying Neighborhood, Jen Douglas

Graduate Doctoral Dissertations

Gentrification of urban neighborhoods is part of an ongoing restructuring of the city, linked to the emerging occupational structure of the service economy and the remaking of built environments that were created for a production economy. It is the name given to processes in which commodification and reinvestment accompany the in-migration of professional and managerial workers, often displacing prior residents and giving altered spatial form to inequality.

This dissertation is a case study of gentrification in Hyde and Jackson Squares, part of Boston's Jamaica Plain neighborhood. The emergence of gentrification pressures and their uneven distribution within the area is documented …

Studying Soil Moisture And Land-To-Water Carbon Export In Urbanized Coastal Areas Using Remotely Sensed Data And A Regional Hydro-Ecological Model, Yun Yang

Graduate Doctoral Dissertations

The main objective of this research was to study the flux of dissolved organic carbon (DOC) from a terrestrial urbanized watershed to an estuarine system using a process-based regional hydro-ecological model and remotely sensed data.

While DOC is an important component of the global carbon cycle, the link of the variations in terrestrial carbon storage is still poorly understood. Soil moisture is a key factor that influences the amount of available water for vegetation growth and the decomposition rate of organic matter in the soil and thus contributes to the amount of DOC in the soil at the land-water boundary. …

Wetlands Utilization And Rural Livelihood Diversification: A Case Of Simiyu Wetland, Magu, Tanzania, Emiliana Mwita

Journal of Humanities and Social Sciences

In many developing countries wetlands play an important role in supporting the livelihood of both urban and rural communities. In rural areas wetlands are increasingly becoming a focal point of production and livelihood diversification due to their richness and the diverse options they provide. This paper explores the livelihood options provided by Simiyu wetland in Magu District, Simiyu Region, to the community living arround it using social survey methods. This paper is based on a study which shows that wetland farming is the main activity (75%) and significantly contribute to cash income generation, followed by livestock keeping, fishing and handicraft. …

Techniques For The Visualization Of Positional Geospatial Uncertainty, Brent A. Barré

LSU New Orleans Theses and Dissertations

Geospatial data almost always contains some amount of uncertainty due to inaccuracies in its acquisition and transformation. While the data is commonly visualized (e.g. on digital maps), there are unanswered needs for visualizing uncertainty along with it. Most research on effectively doing this addresses uncertainty in data values at geospatial positions, e.g. water depth, human population, or land-cover classification. Uncertainty in the data’s geospatial positions themselves (positional uncertainty) has not been previously focused on in this regard. In this thesis, techniques were created for visualizing positional uncertainty using World Vector Shoreline as an example dataset. The techniques consist of a …

Building A Gis Model To Assess Agritourism Potential, Brian G. Baskerville

Department of Geography: Dissertations, Theses, and Student Research

Rural areas of the world are developing and implementing tourism programs to diversify and reinvigorate their local economies. Often, these programs focus on privately-held lands in largely agricultural regions. In some countries, tourism development strategies have combined agriculture and tourism to create a new industry – agritourism. This industry, although not new in the United States, is still in its nascent stages. Before starting an agritourism enterprise, farmers and ranchers must consider the various factors that will likely influence their potential for long-term success. These factors can be grouped into 1) farm-specific factors such as an operator’s personality or the …

Reflections On Community Planning In San Francisco, Rachel Brahinsky, Miriam Chion, Lisa Feldstein

Politics

This paper builds on a dialogue between barrio planners and municipal planners on spatial and economic changes in San Francisco’s Mission District. The Mission is a predominantly Latino neighborhood with vibrant streets that have reflected and been transformed by the investments and displacement of recent decades. Though the Mission has seen tremendous upheaval with the influx of new capital and communities, this paper contends that efforts of community members shaped the development of the neighborhood with street-level planning expertise. We find that an attempt by community members to define their own development proposals and engage in land use decisions– rather …

Jewish Genetic Origins In The Context Of Past Historical And Anthropological Inquiries, John M. Efron

Human Biology Open Access Pre-Prints

The contemporary study of Jewish genetics has a long prehistory dating back to the eighteenth century. Prior to the era of genetics studies of the physical makeup of Jews were undertaken by comparative anatomists and physical anthropologists. In the nineteenth century the field was referred to as “race science.” Believed by many race scientists to be a homogeneous and pure race, Jews occupied a central position in the discourse of race science because they were seen as the control group par excellence to determine the relative primacy of nature or nurture in the development of racial characteristics. In the nineteenth …

Human Biology Open Access Pre-Prints

The origin and history of the Ashkenazi Jewish population have long been of great interest, and advances in high-throughput genetic analysis have recently provided a new approach for investigating these topics. We and others have argued on the basis of genome-wide data that the Ashkenazi Jewish population derives its ancestry from a combination of sources tracing to both Europe and the Middle East. It has been claimed, however, through a reanalysis of some of our data, that a large part of the ancestry of the Ashkenazi population originates with the Khazars, a Turkic-speaking group that lived to the north of …

Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles

Masters Theses & Specialist Projects

Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …

From Generation To Generation: The Genetics Of Jewish Populations, Noah A. Rosenberg, Steven P. Weitzman

Human Biology Open Access Pre-Prints

Introduction:

This year marks the 35th anniversary of two noteworthy papers—one in this journal and the other in the American Journal of Human Genetics—posing the same famous question: are the different Jewish populations from around Europe, the Middle East, and North Africa more genetically similar to each other, or are they more similar to the local non-­‐Jewish populations in the regions where they were historically located? Both studies gathered blood-­‐group and protein variation data from a variety of Jewish and non-­‐Jewish populations, compiling significant “classical marker” data sets commensurate with the standard for human population-­‐ genetic studies at the time. …

Genetics And The Archaeology Of Ancient Israel, Aaron J. Brody, Roy J. King

Human Biology Open Access Pre-Prints

This paper is a call for DNA testing on ancient skeletal materials from the southern Levant to begin to database genetic information of the inhabitants of this crossroads region. Archaeologists and biblical historians view the earliest presence in the region of a group that called itself Israel in the Iron I period, traditionally dated to ca. 1200-1000 BCE. These were in villages in the varied hill countries of the region, contemporary with urban settlements in the coastal plains, inland valleys, and central Hill Country attributed to varied indigenous groups collectively called Canaanite. The remnants of Egyptian imperial presence in the …

Spatial Analysis Of Fatal Automobile Crashes In Nashville, Tn, 2001-2011, Yan Chen

Masters Theses & Specialist Projects

With increasing levels of motor vehicle ownership, automobile crashes have become a serious public issue in the U.S. and around the world. Knowing when, where, and how traffic accidents happen is critical in order to ensure road safety and to plan for adequate road infrastructure. There is a rich body of literature pertaining to time-related fatal crashes, most of which focuses on non-spatial factors such as a driver’s visibility at night, drinking and drug use, and road conditions. These studies provide a theoretical basis for understanding the causes of crashes from a non-spatial perspective, and a number of traffic laws …

Eastern Deciduous Forest Phenology And Vegetative Vigor Trends From 2000 To 2013, Mammoth Cave National Park, Ky, Sean Taylor Hutchison

Masters Theses & Specialist Projects

Global climate change is predicted to affect environmental systems at the midlatitudes, but the scope, severity, and outcomes of these impacts are yet to be fully understood. This study focuses on the implications of short-term climate variability for forests in central Kentucky. Using a Normalized Difference Vegetation Index (NDVI) calculated from MODerate-Resolution Imaging Spectroradiometer (MODIS) instrument data, the photosynthetic activity of vegetation at Mammoth Cave National Park (MACA) is tracked from 2000 to 2013. Three methods were employed to examine the changes and climate influences in vegetation over the study period: 1) aggregating the NDVI of the Park by year …

"We Shall Meet Beyond The River": An Analysis Of The Deathscape Of Brownville, Nebraska, Ashley J. Barnett

Department of Geography: Dissertations, Theses, and Student Research

Gravestone studies have traditionally focused on the East Coast, particularly the Northeast, because of the long Euro-American settlement history in that region and because of a landmark 1966 study produced by Edwin Dethlefsen and James Deetz which focused on this region. Significantly less attention has been paid to the interior of the continent, particularly the Great Plains. This study analyzes the temporal variations in gravestone iconography and inscriptions to determine major cultural shifts that took place in Brownville, Nebraska, from the town’s founding in 1854 to the present. 1,224 gravestones in Walnut Grove Cemetery were recorded and analyzed for the …

Genetics And The History Of The Samaritans: Y-Chromosomal Microsatellites And Genetic Affinity Between Samaritans And Cohanim, Peter J. Oefner, Georg Hõlzl, Peidong Shen, Isaac Shpirer, Dov Gefel, Tal Lavi, Eilon Wolf, Jonathan Cohen, Cengiz Cinnioglu, Peter A. Underhill, Noah A. Rosenberg, Jochen Hochrein, Julie M. Granka, Jossi Hillel, Marcus W. Feldman

Human Biology Open Access Pre-Prints

The Samaritans are a group of some 750 indigenous Middle Eastern people, about half of whom live in Holon, a suburb of Tel Aviv, and the other half near Nablus. The Samaritan population is believed to have numbered more than a million in late Roman times, but less than 150 in 1917. The ancestry of the Samaritans has been subject to controversy from late Biblical times to the present. In this study, liquid chromatographyelectrospray ionization quadrupole ion trap mass spectrometry was used to allelotype 13 Y-chromosomal and 15 autosomal microsatellites in a sample of 12 Samaritans chosen to have as …

Ordinary Families: Queer Sexuality And Adoptive Parenthood In Central New York, Sean H. Wang

Theses - ALL

This thesis argues that geographers must consider sexuality and family together as integral parts of social life. Although sexuality already entered the lexicon of geography in the 1980s, and a burgeoning field of the geography of sexuality exists today, too often it is still considered peripheral in geographic scholarship. Similarly, family either remains consigned either as merely a place for social reproduction by studies of political economy, or is relegated entirely as an object of inquiry for only feminist geographers. Drawing from sociology, feminist and queer studies, this thesis makes an important intervention by relating sexuality and family in the …

House Broken: The Functions And Contradictions Of "Housing First", Brian Richard Hennigan

Theses - ALL

"Housing first" is the new orthodoxy for homelessness policy in the United States, a program design expected to end homelessness once and for all. Unlike the traditional "treatment first" model, housing first places the most expensively homeless individuals immediately into an apartment (with treatment following). Although certainly different from the treatment first model due to its prioritization of housing, housing first remains a product of neoliberal poverty governance. By examining program operations in greater Phoenix, Arizona, it is clear that housing first proceeds as a stigma-reproducing rehabilitation program of socioeconomic discipline that works in tandem with anti-homeless laws and service …

Legislated Landscape: A Comparison Of New Deal Farm Communities In Hattiesburg, Mccomb, And Tupelo, Mississippi, Joy Delaine Rhoads

Master's Theses

Government New Deal farm policies of the 1930s changed the realities of farming and the landscape in Mississippi. This research endeavors to compare three farm communities created by New Deal legislation in the state: Hattiesburg, McComb, and Tupelo. The economic crisis that was the Great Depression created a highly politicized environment as citizens looked to the government for economic relief. A crisis this severe would require an exceptional effort to mitigate the economic hardships it created, in varying degrees, for millions of Americans. The actions of the federal government during the Great Depression were an interesting mix of paternalism, desperation, …

A Decent Place To Stay: Housing Crises, Failed Laws, And Property Conflicts In Washington, D.C, Katie Jeanne Wells

Dissertations - ALL

In 1978 the District of Columbia City Council enacted a measure to tax up to 97 percent of the profits on speculative housing sales. In 1984 the District of Columbia voters approved an initiative to guarantee every resident who needed it access to overnight shelter for every night of the year. Both of these responses to the city's housing crisis marked the beginning of a politically progressive moment in Washington, D.C., when residents won the right to self-governance after a century of Congressional control and the majority-black electorate created a majority-black legislature of civil-right activists. But both laws were made …

Spatiotemporal Patterns And Socioeconomic Contexts Of Vegetative Cover In Altamira City, Brazil, Scott Hetrick, Rinku Roy Chowdhury, Eduardo Brondizio, Emilio Moran

Geography

Ecosystem services provided by urban vegetation can ameliorate problems common to urban environments while improving the quality of life of urban residents. Much research in urban ecology has analyzed urban environmental dynamics in the global north; rapidly urbanizing areas in the global south have not received commensurate attention. The land cover dynamics of mid-sized cities in the global south remain under-explored in particular. In this article, we investigate the spatial patterns and socioeconomic contexts of urban vegetation in Altamira, Brazil, a mid-sized but rapidly expanding city in the Amazon. Using time series remotely sensed imagery, we profile changes in urban …

Temperature Trends And Urban Heat Island Intensity Mapping Of The Las Vegas Valley, Adam Leland Black

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modified urban climate regions that are warmer than rural areas at night are referred to as Urban Heat Islands or UHI. Islands of warmer air over a city can be 12 degrees Celsius greater than the surrounding cooler air. The exponential growth in Las Vegas for the last two decades provides an opportunity to detect gradual temperature changes influenced by an increasing presence of urban materials. This thesis compares ground based thermometric observations and satellite based remote sensing temperature observations to identify temperature trends and UHI areas caused by urban development.

Analysis of temperature trends between 2000 and 2010 at …

For Logs, For Traditional Purposes And For Food: Identification Of Multiple-Use Plant Species Of Northern Amazonia And An Assessment Of Factors Associated With Their Distribution, Anthony Ravindra Cummings

Dissertations - ALL

This dissertation examines the multiplicity of uses associated with tree and palm species of the Rupununi, Southern Guyana and the factors associated with their distribution. As tropical forests continue to decline the most significant response has been to understand the implications for the carbon cycle, with the impacts on forest dwelling peoples and wildlife, inadequately addressed. Multiple-use plants, individual species which at their most critical level provide food for wildlife, non-timber forest products and are commercially logged, provide a suitable lens for appreciating additional ecosystem services that may be compromised as tropical forests decline. I completed a plant inventory in …
